Alzheimer's Tau Platform: Master Protocol

The goal of the Alzheimer's Tau Platform (ATP) is to evaluate the safety and effectiveness of tau-directed therapies, alone or in combination with the anti-amyloid monoclonal antibody, donanemab, in adults aged 50-80 with late preclinical or early prodromal Alzheimer's disease. This platform trial allows for the simultaneous testing of multiple tau therapies under a shared master protocol. This means that multiple investigational products will be tested simultaneously or sequentially. Each investigational product will be tested in a regimen. The main questions the platform trial aims to answer are: * Does a tau-directed therapy, alone or in combination with donanemab, reduce tau buildup in the brain compared to donanemab alone? * Does a tau-directed therapy, alone or in combination with donanemab, slow disease progression based on brain imaging, fluid biomarkers, and measures of memory and thinking? Participants will: * Be randomized to a treatment regimens, each containing different tau therapies. The exact number of treatment regimens that will active at the time of screening will change over time. * Receive donanemab or placebo for 6 months, followed by 24 months of tau therapy alone or in combination with donanemab. * Undergo regular cognitive testing, brain scans (MRI/PET), and biomarker assessments over 30 months Participants will have an equal chance to be randomized to all regimens that are active at the time of screening. Once randomized to a regimen, participa…
